| 10 | B | Model year — 1981 |
| 11 | × | Assembly plant |

Where this data comes from
Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.
Vehicle counts come from the 36 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
